It seems grass existed on Earth at least 10 million years earlier than was known, based on a new discovery in fossilized dinosaur dung.
It's also the first solid evidence that some dinosaurs ate grass.
While dissecting fossilized droppings, known as coprolites, researchers found tiny silica structures called phytoliths. They are short, rigid cells that provide support to a plant. This type is found exclusively in grasses.
The discovery shows that five types of grass related to modern varieties were present in the Gondwana region of the Indian subcontinent during the late Cretaceous period about 71 to 65 million years ago. http://www.technovelgy.com/Bjorn Carey (LiveScience Staff Writer)
So the oldest evidence for grass comes from the upper Cretaceous, which is 230 million years after the world wide Carboniferous coal measures were formed. Or you could look at it this way, the Permian, Triassic, Jurassic and Lower Cretaceous are completely devoid of any grass fossils. Plenty of time for evolution to come up with a novel way of growth, which is one of the hallmarks of grass, i.e. grass grows from its base, unlike other plants that grow from their tips.
This is not easily explained by creationist parodies, but I am willing to look at any ideas creationists might have, come on give it a go.
